To all whom it Wing concern.-

Be itknown thatwe, BARRY lvoR and JOHN S. W'ABD, citizens of the United States, residing at Chicago, in the county of Cook and State of liiinois, have invented certain new and useful Improvements in Force-Feed Luloricators, of which the following is a specification. 1

This invention'relates-to improvements in that class of luhricators or small pumps employed for forcing oil to any part or parts that it is desired to have constantly and uniformlylubricated; and it consists in certain peculiarities of'the construction, novel a'rrangement, and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The objects of our invention are to provide a luoricator which shall he compact in form, positive, direct, and unifiorm or even in operation, and so constructed that one or.

more pumps may be supplied with oil by the same reserv'oir'and may be operated by'the same driving mechanism,

Another object is to so construct and arrange the different parts-of the apparatus that the oil-reservoir will be located near and usually above the steam-engine used for.op-'

4 eratingghe pumps, thus keeping the oil warm by m ca s of the heat from the engine, so that it wili ow freely.

A further object is to provide means for automatically lubricating the frictional parts of the apparatus and also to indicate the quantity of oil being pumped as well as the movement of the drivingshaft;

/ Still another object is to provide means for forcing oi from the reservoir by means of a hand-pump. I t I Other objects and ad vantages of the invention will be disclosedi'n the subjoined descriptiou and explanation.

In order to enable others skilled in the art to whichour invention pertains to make and use the same, we will now proceed to describe it, referring to the accompanying drawings, in which- Figurql is a front view, partly in section and partly in elevation, of a lubricator embodying our invention. Fig. 2 is a view,

partly in section and partlyin elevation, taken on line 2 2 of Fig. 1 looking in the direction indicated by the arrows, but showing the casing over the driving-gear removed. Fig. 3 is a view in elevation of a portion of the driving-shafts, illustrating" the clutch mechanism thereon. Fig. 4 is a sectional view thereof, takenon line 4 of Fig. 1, looking in the direction" indicated by the arrows. Fig. 5 is a vertical sectional view of the upper portion of one of the pumps, showing the construction of the oil-indicator thereon. Fig. 6 is a sectional view, taken on line 6 6 of Fig.

1, of the brake, showing it applied to the driv- The numeral 15 represents the bracket used for supporting the casing or main frame 16, which bracket may be seen red to a suitable support by meansof bolts passing through openings 17 in its top and bottom. The casing or main frame 16 is preferably rectangular in shape and may have its front portion closed by means of a door, which maybe fastened by means of a seal, thus preventing access to and tampering-with the adjusting devices of the lubricator. The lower portion of the nfain frame or casing 16 is formed with a nnm her of receptacles 18 to form oil-wells for lubricating certain parts of the machine. The casing 16 is preferably provided with a horizontal partition 19, on which is supported the steam-engine 20, used for operating the pump, and which engine may be of the ordinary or any preferred construction; but as we do not olaim'any hing new in the engine itself we will describdsuoh parts thereof only as will'he necessary for the proper understanding of the operation of our apparatus. This engine consists of a cylinder 21, a piston 22, and a reciprocating piston-rod 23, with the necessary valves, ports, and packing to render it operative. Located on the upper portion of the casing or main frame 16 is the oil-reservoir 24, which is provided with a supply-pipe 25, having at its upper end a removable plug or cap 26 to close the LIA a: a v v 734,069

same. One end of thereservoir is provided with a sight-gage fllg of the ordinary construction, nsed'to indicate the quantity of oil contained therein. The front lower portion of the reservoir is preferably provided with an offset 26 for the reception of a portion of the pumps, as will be presently explained. Horizontally journaled in the lover portion of the casing or main frame 16, just above the wells 18 therein, are the driving-shafts 2.) and 30, the latter being used as an auxiliary shai't when it is desired to operate all of the pumps. Due end of the shaft 29 extends through the main frameand is screw threaded, as shown in Fig. 10f the drawings. Located on the screw-thrcadcd portion of the shaft 529 is a raj chet-wlieel Ill, which rotates with said shaft,-ahd loosely mounted (and preferably on hall-hearings 32) on the shaft outside of the ratchel vheel is a beveled gear 33, which is preferatjly of the mutilated type-that is, it preferably has portions only of its face provided with beveled near-teeth; buta complete beveled gear may be employed. This gear is provided on its periphery with flanges 34-, toeach of which is pivotally secured a pawl 35, Which are held in engagement with the ratchet -wheel by means of springs 36, as is shown in Fig. 2 of the drawings. Placed over the ratchet-wheel 3i. and gear 33 and secured to l .0 end of the mainframe 1G is a casing 37, which will exclude dust and has on its face a scale orgraduate marks 38, used in vanilla-lion with the pointer 39, fixed on the outer end. ot the d l'l\'lD,I-Sll2tfl3 2! to indicate. the movement of the driving-shaft and the ratchet-wheel, which is fixed thereon. Fixed to the shalt. Sf), within the casing 16, is a collar ll), against which impinges a brake-shoe ll, which provided with a headed stem i2,

located in a tube 42l,'extending' through the front part of the casing or main frame. The outer end of this tube is internally screwthreaded to receive a screw 44, between the inner end of which and the head of the stem of the l rakeshoe is locat d a spring 45 to keep said shoe in contact with the collar 40 on the driving-shalt. Fixed on the end of the shaft :10, or auxiliary shaft, adjacent to the shaft 25), is a collar 46, which is provided with a pin 47 to engage an opening 48 in the collar 4!), which is slidably mounted on the shaft 25), with means to prevent turning on the same, and is provided with an annular groove 5C for the reception and operation of rollers 51, journaled on the ends of the yoke 52, which has secured .to one of its ends'a lever 53, which is fulcrumed on the front portionof the casing, or main frame. Enough space is left between the walls of the groove 50 and the rollers 51 to allow them to properly cooperate vi h said walls when the lever 53 is turned on its fulcrum toshift the position of the slidable collar. Secured to the outer sur tace of the casing 16 is a segment 54L, which has notches 55 to receive the end of the springactuated grip rod 56, which is pivoted to the be presently explained.

lever 53, as shown in Fig. t of the drawings. By turning the lever 53on its fulcrum it is apparent that the collar 52 will he slid on the driving-shaft, so as to connect it or disconnect it with the collar 46, thus coupling the shafts 2.) and 30 togetheror uncoupling them, as desired.

In Fig. 1 of the drawings, W6 have shown the apparatus as having four pum ps to be operated by the steam-engine, two of which, 57 and 58, are operated by the main shaft 29 and the other two, 5!) and (50, are operated by the auxiliary shaft. Between the pair of pumps 57 and 5S and between the pair of pninps 59 and 60 is located a vertical guidepiece ill or hearing for the rods 62, and said guide or hearing pieces are formed at their upper ends with cups 63 for oil for said rods. The lower end of each of these rods is screwed into a suitable socket (it on a band 65, which surrounds an eccentric 66, secured by means of set-screws (37 or otherwise to one of the main driving-shafts at a point below and between each pair of pumps. These pumps are of the same construction, and each consists of a vertical cylindrical portion 68 and a horizontal portion 69, which extends rearwardly and is secured to the front portion of the offset 28 of the reservoir by means of bolts 70. The lower portion of the cylindrical part 68 is formed with a stuffing-box 71, in which is suitable packing 72 and a gland or follower '73, surrounding the piston '74, which extends into the cavity 75 of the pump and has on its lower portion an annular shoulder 76, against which the adjustable cross-bar 78 may rest, as will The upper portion of the cylimlrical part 68 is internally screwthreaded to receive the screw-threaded. portion of a plug or cap 79, which is provided with a valve'chamher SO and outlet-openings 81. Located in the valve chamber 80, so as to close the channel 75, is a hall-valve 8 Extending horizontally from the front outer portion of the cylindrical part (58, through the cavity or oil-chamber 75 thereof, and into the horizontal portion 69 is an openin r83, which is closed by means of a screws-ping 8; and

which forms the horizontal valve-chamber S5, in which is located aball-valvc 86, which opens and closes the port 8? when theplston '74 is retracted and ad vanced. The valvechamber 85 communicates with the oil-cham her 75 through ports 88 in a plug located in the outer end of the chamber 85, and the port 87 has communication. with the valvechamber 89 in the horizontal portion 69, said valve-chamber 8.) being formed of a hollow and open screw-plug, '00, secured into a suitable opening in said horizontal pontion. The valve-chamber provided with a ballvalve 91 to close the port 92, which communicates with the pipe 93 opening into the reservoir.

The lower portion of the pipe 93 is formed with an opening 9%, which is closed by means of a plug 95, and which opening is for the about its middle is an extension 98, which is hollow and has an upwardly-extending arm 99, provided with a scale 100. Located in the opening of the extension 98 isa pistonrod 101, which is provided on its outer portion with enlargements 102 to act on the lower end of the pointer 103, which is pivotaily so cured to the arm 99 and is used in connection with the scale 100 to indicate the quantity of oil that is being forced through the tubular piece 96 and oil-pipe. The upper end of the tubular piece 96 is provided with a spring-pressed hall-valve 101 to normally close the opening in the tubular piece. By

taking hold of the knob or thumb-niece with the hand on the outer end of the rod 101 and pressing it inwardly to the position shown in Fig. 5 it is apparent that as the oil is forced through the tubular piece 96 the piston-rod will he forcedoutwardly, thus causing one of The projections 102 to impinge the lower end of the pointer103 and toindicate on the scale the rate of stroke of the pump-piston. The lower portion of each of the pistousj' is screw-threaded to receive the jam-nuts 105 and the wing-nuts 106, used for removably connecting the crossbar 78 to the piston-rods, as is clearly shown in Fig. 1 of the drawings. The cross-bar '78 may be adjustably secured to'the rod 62 by means of a setscrew 107 passing through its central portion, and a nut turning them on the rods 62 and without removing the nuts 105 and 106, as is apparent. Secured to the outer end of the piston-rod 23 by means of a collar 109 and a set'screw 110 is a cross-head 111, having a slot 112, in

which is adjustablysecured, by means of nuts 113 and 114, a bolt 115, which has on its end a head 116 and passes through a slot 117 in a crank 11S, whichis secured on the end of a shaft 119, journaled, preferably, in ball-bearings 120 on the lower portion of the main frame and at right angles to the main driving-shaft. Mount-ed on the shaft 119 is a beveled gear 121, which meshes with the beveled gear 33 on the driving-shaft. Communicating through a pipe '122 with the rear portion of the reservoir is a hand-pump 123, which is provided at one of its ends with a stuffingdiox 12% and a gland or follower 125, surrounding the piston-rod 126., which has on its outer end a hand-wheel 127 and on its innor end a piston 128 to pperate in the cavity 129 of the pump-cylinder, which channel or, cavity communicates with the oii chamher 130, which is closed by means of a screw-cap 131 on the opposite end of the pump-cylinder from that on which the gland is located. Communicating with the lower portion of the oil-chamber and with the pipe 122 is a valve-chamber 132, which is provided with a ball-valve 133 to open and close the same. Secured on the upper portion of the pump cylinder 123 is a piece 134, having a valvechamber 135, coniniiinicating with the upper portion of the oil-chamber and also with the branch pipes 136, to each of which may be secured a pipe 1.37, leading to any desired point or part to be lubricated; but in the present instance we have shown the pipe 137.

provided with a shntpfi valve 138 and communicating with one of the pipes 97, leading from the engine-pumps.

From the foregoing and by reference to the drawings it will be clearly seen and. readily understood that by the reciprocation of the piston-rod 23 of the engine and its connection with the shaft 119 said shaft and the gear 121 which it carries wiii be rocked hack and forth, thus imparting an oscillatory motion to the gear 33, which by means of its pawls 35 will cause the ratchet-wheel 31' and the driving-shaft 29 to be intermittently rctated, in which operation the piston-rods M of the pumps will be intermittently reciprocated by reason of their connection through the cross-bar 78 with the rod 62 and its eccentric connection with thedriving-shaft. When it is desired to operate all of the pumps, the
